I've found that if you tell them that anniversaries and the entire wedding arrangement (ceremony and rings) are of pagan origin, most Jdubs STFU.
I go even further by educating them on how make-up, jewelry and the braiding of hair was condemned in the bible and of pagan origin.
A few months ago I spoke with an Elder and some ministerial servants at a gathering and asked them, "Why is it that we do not follow the jewish traditions or festivals which Jesus celebrated/followed?" They were a bit stumped but they began reasoning that Jehovah lost favor with the Jews when they killed Jesus and so the Jewish religion and its traditions are apostate.
Everything is either pagan or apostate if it doesnt originate with the Watchtower Society. Even practices found in early Christianity from the 1st century later is considered apostate christendom. These cult leaders are such hypocritical debbie downers
